WILLIAM nnon'r, ornosnmnmr, nonrn cenonnvm l sacrum-3mm To all whom it may concern:

-.Be it known that I, WILLIAM B. How, a citizen 'of'the .United States, residing at Rosemary, in the county of Halifaxand 5 State of North Carolina, have invented cer-.

tain new and useful mprovements in Shuttle-Binders, of which the followingis a specification, reference being had to the accompanying drawings.

and particularly to binders designed to work in connection with magazine :looms having :feeler motions.

The general object of my invention is to provide a very simple binder adapted to work in connection" with the .Crompton- Knowles magazine loomand the. Draper automatic loom, which will l'do away with the necessity of check straps,binder springs,

less power, whereby the shuttle maybe held in position so that there is -no breakage of bobbins when the magazine makes its change .and whereby neither damp nor dry weather will aflect the shuttle box' when the binder is used. And a further object is to provide a binder construction which will not cause theshuttle to rebind and which will hold the shuttle parallel to the line of the back box, provid-. ing for a .chang'e'of bobbins in magazine looms without any liability to breakage.

A further object is to rovide a binder whichwill check the shutt e very gradually at firstzand which then acts to offer more resistanceto the shuttle, causing. theshuttle toireach its destination without any rebin d or bouncing, thus eliminating trouble given by all ordinary binders. 4o in .her object is to provide a binder which, after the shuttle has'reached its destination, will be pressed outward at theforward end by the shuttle, thereby pressing just sufficient on the middle of the shuttle as to place the shuttle inparallel l ine'wlth the back of the shuttle box so that the mag? azine. mechanism 1 has full chance to 7 pass the bobbin through the shuttle onexchang- 1n L I 7 .50 a further object is to providea binder which will have a quickandeasy release when the loom makes its pick, thus saving considerable power in operati the loom. further object'is to provide a binder which maybe easily, adjusted tosuiti different sized shuttles andbwliich will opti- Speciflcatlonot Letters iatent.

This invention relates to shuttle binders,

etc., and whereby the loom may be run with angle' to each other." Rivetedor other 186 Patentedseptftfi, 1919.

.the arm 22 extends toward'the opposite 'end of the lay beam. The arm'32 2 s jnwa rdly bowed and gradually curved, jandfthejarx'n 21 is also inwardly bowed,. the chords 'ofithe arcs of the twoarmsbeing"disposedl agtyan attached to the innerflfaceof Qthe'ar ns: 21 4 l and 22 is a leather strap 25.

then .being outwardly and rearwardly inclined at a very slight angle, as at 2, so

.that the extremity (if the spring" lies flat against the strap 25. The strap naturally maintains itself on a straight line across the" triangular. space 28, but the sprm resists'inward movement of the strap. ref

er'ably, the ears 24 are slotted and the pin- '23- or' studis adjustable in. said slot so as to shift the binder inward or outward relative to the shuttle'b'ox. I have not deemed it necessary to, show the feeler nor the protecting rod mechanism, nor any ofthe other or usual partswhich do not intimately coact with the binder. I i

In the operation of this device, when the shuttle enters the box the binder-i begins, to

cgeck the shuttle; at the point A, gradually e ecking it, until the shuttle strikes the ,ieather strap andfl forces the leather strap I against the steel spring 32 at B. \Vhen the shuttle reaches the point C, the checking.

of operation in order to change'the bobbin.

It will be noted that the arm 21 bears against the shuttle over a distance not more than 115'" from d to d in Fig. 1. This gives a very quick and easy release so that the l'oom when it makes its pick will throw the shuttle withvery. little power, and it will also be'noted that as soon as the eye end of the shuttle commences to move outward .under the action of a pick, the pressure of the arm 22 on the shuttle is relieved. Vhen this binder is set. it remains in its adjusted position until it is changed, and when it-is desired to use different sized shuttles, the binder is easily' adjusted by loosening the binder stud 23 and moving the binder inwardor outward 'to suit the size of the shuttle.

It will be noted also that the binder is verysubstantial, heavy, and has no bolts to work loose and give trouble. In actual test, the speed of a loom with this binder has been changed from 15 to 20 revolutions per. minute without changing the binder in the least and without aiiectingthe,proper operation of the hinder. or without causing the loom to bang ofi. The binder does away with all check stralp's, binder springs, etc., found on the Crompton-Knowles loom and Draper loom. It places and holds the shuttle in position so that there is no breaknor does damp age of bobbins when the; magazine'ma-kes its change. The shuttle does not ,;.'rebind, or dry. weather aifect the shuttle bOX.' It holds the shuttle paral- 1 lel and in line with the back box, giving the magazines on. the Crompton-Knowles loom or the battery on the Draper loom atropportunity to make a change in bobbin without any hang up or breakage.

It Will be noted that'the space 28 isrelatively long and that for this relatively long distance thestrap 25 is unsupported save by a portion of the 'spring 32, so that the 'forward portion of the strapconforms to the curvature of the forward end of the shuttle, but the middle portion of the strap exerts relatively light. pressure against the shuttle and that the shuttle will release very quickly for the. reason thatas soon as the shuttle commences to move out of the box under the action of the picker stick,it moves away from the aface of the strap. The spring 32 increases the check on the; shuttle before the shuttle reaches its destination but the shuttle reaches its destination with much more easethan itwould Without thespringj The curve in the strap between the point B and-the pointD or a little beyond the point D is such that the strap is pressed against. the shuttle at this point by-the spring'32.

Oneof the great advantages of my binder is that it'permits the loom to be run with a slack protector rod spring. Thiseliminates.

wear on the shuttle and this slack protector rod'spring permits the binder to operate 'properly where the loom. is running with considerable variations in speed. These advantages are secured by the fact that with my binder the shuttle requires but a slight .movement in order to release.-

I am aware of Patents Nos. 1,053,066 and 958,487, which show binders similar to mine, but with bindersof this character, the check, is very severe from the starting point until the shuttle reaches the back of the ,box. This causes a great wear on shuttles, binder studs, shuttle binders, protector rodsprings, and protecting fingers. It also causes wear on the cam point-s, cam'balls, lug straps, and is liable to cause breakage of the picker sticks. This is-due to the fact that with binders of the character shown in these patents, a very tightprotector rod spring is. necessary: The shuttle illustrated in these patents does not release as ,easily or quickly.

and bearing against the inner face of the strap midway between the arms.

3. In a loom, the combination with a shuttle box, of a binder therefor having two inwardly arcuate arms of different lengths, the binder being ivotally supported at the j unction of said arms, the shortarm extending toward the adjacent end of the lay beam and the long arm extending toward the other end of the lay beam, the chords ofsaid arms being disposed in angular relation to each other, a strap attached at its end to the inner face of the extremity-of the short arm and at its other end attached to the inner face of the long arm adjacent its extremity, said strap extending acrossthe triangular space defined between said arms, and a flat leaf spring attached to theinner face of one arm and bearing against the inner face of the strap and resisting inward movement of the strap,

4. In a loom, the combination with a lay beam and shuttle box, of a binder pivotally mounted for movement toward or from the shuttle box, the binder comprising two arclrate arms integrally connected with each other,the binder being pivoted to the inner section of the arm, and the chords of the arms being in angular relation to each other, one of the arms being relatively short and extending to the end of the box and the adjacent end of the lay beam, the other arm being relatively long and extending toward the opposite end of the lay beam, a leather, strap attached to the extremity of the short arm and extending, over the curved inner face of the long arm' and attached to the adjacent extremity thereof, said strap extend ing taut across the substantially triangular space between said arms, and a flat spring leaf attached to the inner ends of the-long arm in said triangular space and extending outward-and lying fiat against the inner face of the strap and resisting inward movement of the strap -5. In a loom, the combination with a shuttle box, of a binder therefor having two an-.

gularly disposed, inwardly bowed arms, and a strap attached to the inner faces ofsaid arms and extending across the triangular space defined between said arms, the binder being pivotally mounted on the shuttle box at a point substantially at .the junction of the two arms.

In testimony whereof signature.
